摘要:
A plurality of isolated polynucleotide sequences encoding enzymes of the astaxanthin pathway is disclosed. The polynucleotides include: (i) a polynucleotide which encodes Phytoene dehydrogenase (crtI) and a first transcriptional regulatory sequence; (ii) a polynucleotide which encodes Beta-lycopene cyclase (lcy-B) and a second transcriptional regulatory sequence; (iii) a polynucleotide which encodes Beta-carotene ketolase (crtW) and a third transcriptional regulatory sequence; and wherein the first, second and third regulatory sequence are selected such that the expression of the Icy-B and the crtW is greater than a level of expression of the crtI. Methods of generating astaxanthin using the plurality of polynucleotide are also disclosed as well as bacterial cells comprising high levels of astaxanthin.
摘要:
A unique carotenogenic biosynthetic gene cluster has been isolated from Panteoa agglomerans strain DC404, wherein the genetic organization of the cluster is crtE-idi-crtY-crtI-crtB-crtZ. The genes contained within this cluster encode geranylgeranyl pyrophosphate (GGPP) synthetase (CrtE), isopentenyl pyrophosphate isomerase (Idi), lycopene cyclase (CrtY), phytoene desaturase (CrtI), phytoene synthase (CrtB), and β-carotene hydroxylase (CrtZ). The gene cluster, genes and their products are useful for the conversion of farnesyl pyrophosphate to carotenoids. Vectors containing those DNA segments, host cells containing the vectors and methods for producing those enzymes by recombinant DNA technology in transformed host organisms are disclosed.
摘要:
Membranous bacteria that produce astaxanthin and other carotenoids are described, as well as isolated nucleic acids and expression vectors that can be used for producing carotenoids in microorganisms.
摘要:
A cDNA encoding geranylgeranyl diphosphate synthase from Canadian Yew (Taxus canadensis) has been isolated and sequenced, and the corresponding amino acid sequence has been determined. Accordingly, an isolated DNA sequence (SEQ NO:1) is provided which codes for the expression of geranylgeranyl diphosphate synthase (SEQ ID NO:2), from Canadian Yew (Taxus canadensis). In other aspects, replicable recombinant cloning vehicles are provided which code for geranylgeranyl diphosphate synthase, or for a base sequence sufficiently complementary to at least a portion of geranylgeranyl diphosphate synthase DNA or RNA to enable hybridization therewith. In yet other aspects, modified host cells are provided that have been transformed, transfected, infected and/or injected with a recombinant cloning vehicle and/or DNA sequence encoding geranylgeranyl disphosphate synthase. Thus, systems and methods are provided for the recombinant expression of the aforementioned recombinant geranylgeranyl diphosphate synthase that may be used to facilitate its production, isolation and purification in significant amounts. Recombinant geranylgeranyl diphosphate synthase may be used to obtain expression or enhanced expression of geranylgeranyl diphosphate synthase in plants in order to enhance the production of geranylgeranyl diphosphate, or diterpenes derived therefrom, or may be otherwise employed for the regulation or expression of geranylgeranyl diphosphate synthase, or the production of its products.
